Explanation Calculation: Consider the provided coordinates of the point in x y -coordinate, x , y = 3 , 1 Now, consider the angle of rotation θ for the x ′ y ′ -coordinate system. θ = 60 ° The relationship between the coordinates of x y -coordinate system and x ′ y ′ -coordinate system is: x = x ′ cos θ − y ′ sin θ y = x ′ sin θ + y ′ cos θ Now, substitute the provided coordinates x , y = 3 , 1 and the angle of rotation θ = 60 ° in the above relation. 3 = x ′ cos 60 ° − y ′ sin 60 ° ...... (1) And 1 = x ′ s i n 60 ° + y ′ c o s 60 ° ...... (2) Now, solve equation 1 , 3 = x ′ 1 2 − y ′ 3 2 And, x ′ − 3 y ′ = 6 ...... (3) Now, solve equation 2 , 1 = x ′ 3 2 + y ′ 1 2 And 3 x ′ + y ′ = 2 ...... (4) Now, apply the substitution method in the equations 3 and 4 . Substitute the value x ′ = 6 + 3 y ′ from equation 4 in equation 3

Question

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
